the degenerated dxy, dxzand dyzorbitals in Ohsymmetry split into a completely filled egband and an empty a1gband for D3dsymmetry. Interestingly, the orbital splitting can be reduced in half-disordered structure with D'3dsymmetry, in which the egelectrons can easily hop...
We determine the phase diagram of the half-filled two-leg ladder both at weak and strong coupling, taking into account the Cu d_{x^2-y^2} and the O p_x and p_y orbitals. At weak coupling, renormalization group flows are interpreted with the use of bosonization. Two different models ...
TMDs are more stable with a unique defect structure due to the existence of lone pair d electrons and empty d orbitals that are easy to bond, as well as the high charge/radius ratio of atoms or ions. Among them, MoSe2 possesses several appealing features, including a large interlayer ...
Ferromagnetism is most common in transition metal compounds where electrons occupy highly localized d orbitals. However, ferromagnetic order may also arise in low-density two-dimensional electron systems1–5. Here we show that gate-tuned van Hove singula
A net magnetic moment of 1μB and 2μB are, respectively, found in the B- and C-doped structures mainly due to the partially filled dopant atom 2 p orbitals. Due to ferromagnetic coupling, magnetic moments from the neighbouring Zn atoms and the subsequent O atoms also contribute to the ...
predicted the charge transfer from the empty d-orbital (d0) of V to half-filled d-orbital (d5) of Fe can trigger a non-bulk-like charge configuration, resulting in a polarization comparable to some of the standard single ferroelectric perovskite oxide like BaTiO3, BiFeO3 etc. Show abstract...
The values calculated with screening are displayed with filled circles and those without screening are plotted with empty symbols. The dashed lines are given to guide the eye. (b) Calculated PSF for EC as a function of the mass number of the parent nucleus. The filled circles display the ...
Electronegativity increases as a valence shell is filled, but decreases for atoms (and molecules) with full shells Basically, electronegativity is a measure of the propensity for an atom to be able to form bonds, and how strong those bonds will be. The higher the electronegativity is, the ...

To explore how to achieve FM in LHDPs, first, we bring the origin of the AFM behavior in Cs4Mn2+Sb3+2Cl12LHDP, as observed in recent experiment,24to light. Based on the crystal field theory, the fivedorbitals of Mn will split into a singletAlg(dz2), doubletEg(dxz + dyz), ...
